Chicago - Jeff Bianchi delivered a two-run single off shortstop Starlin Castro's glove with two out in the ninth to lead the Milwaukee Brewers to a 3-2 victory over the Chicago Cubs and a day-night doubleheader sweep on Tuesday. The Brewers pulled out the nightcap after a 6-5 victory in which they lost starter Yovani Gallardo to a tight left hamstring. In the second game, they got six scoreless innings from Tyler Thornburg and a leadoff homer from Juan Francisco in the fifth. But they had to rally after David DeJesus delivered a two-run double off Burke Badenhop following a pair of errors in the seventh. Chicago took a 2-1 lead to the ninth, but closer Kevin Gregg (2-3) couldn't hold it.
